1981 VW caddy high idle.

[Petebee]

I feel your pain. I'm trying to resurrect an 81 Scirocco S that has not run in 16 years. I've got it to where it will idle decent and run for about 5 minutes, then it bogs and dies.

Finally got this little tool to test fuel control pressures as I suspect my warm up regulator is out of whack.

Your Caddy sounds like it is the fuel mixture...especially since you are unable to adjust it. Idle adjustment screw and timing could be off as well.

I've come close to carbs, but I'm trying to keep this one fairly OEM.

Good luck!

if you can get a side draft manifold , ive got a nice pair of dellorto 40s off a 1600cc alfa that i will sell you. jetting should be reasonably close

weber 2 barrel is a good carb.if jetted properly it will run well. do you own a wideband O2 ? most carbs will run less than perfect before the engine is warm. i have several machines on carbs and i like them ,it all depends on what you think is "just fine"

No thanks, not interested in spending a bunch of money.

that would be pimp.

Electric choke is good, but damn dude. That's a lot of coin. Plus you'll need to use a different fuel pump.

that's fine with me.

Something like this, K402

If you go Weber DGV I'd suggest that you

be sure and get a REAL Weber vs. shitty a Chinese copy. I think they're made in Spain now.

check the throttle shaft for slop if you shop used because this is a "special feature" that develops over time in the DGV's and creates nasty vacuum leaks.

go with a manual choke vs water choke. they leak and they suck and you're in Cali so your choke needs are minimal anyway.

danny I have rims for your caddy. bbs rd037 , 15x7 4x108 :D

[Danny]

But would it run and drive just fine? Idc much for "right"

[der affe]

a weber progressive on that motor is like a hot girl with a 14" cock.......
it's just not right!

[Danny]

I was just gonna do a single weber carb conversion. Thoughts?

[Ryann]

With a little patience, a good manual, and and a multimeter you could sort it out and it'd out perform a shitty carb setup. In like, an hour. Although based on your pp's it sounds like some asshole tried to mess with it and fucked it up.

[der affe]

did you ever get your hands on a fuel pressure tester for CIS?
start at the back and work forward........or badger5.......

CIS isn't that bad, it is just different.
i felt the same way when i wnet from CIS to pulsed injection. it is a learning curve
